How long do you think until 1080p 50/60Hz brodcasts are available?

I was thinking, is it possible to get a 1080p broadcast picture at 50/60 frames per second, and if it is, how long do you think until it happens? Also, is cost going to be another issue, as WWE has spent $20mil. on upgrading to HD which is being displayed at 1080i and if 1080p broadcast is achieved, do you think it will cost anything to upgrade for the faster passed sports, i.e. Olympic events, high flying wrestling matches, etc.

One more thing, why don't movie channels display 1080p movies at 24fps (including ad breaks incase it will be troublesome to switch from 60fps 1080i during ad's to 24fps 1080p during movies), cos, I mean, isn't there enough bandwith in the air to display programmes at under 30fps in 1080p? Let me know what you have to say on this.

Terrestrial bandwidth is the biggest limiting factor. It may be about 15 to 20 years before you see a 1080p broadcast, if that soon.

Unfortunatly, by that time, we probably might have moved on to UHDTV.

Honestly, unless every home is equipped with full wall-sized screens in the future there is not much point in broadcasting in UHDTV. Not to mention files sizes measured in terabytes. That idea seems a little too far fetched for the consumer market right now.

Currently film and professional video is shot at 1080P/24. I would love to see someone develop a new recording system that did 1080P/60 or higher. The required bandwidth and the need for several TB’s of recording space is keeping the industry at 24fps. Maybe in the future a new film or video format will offer 60fps or higher native recording rate.
The problem with broadcasting in 1080P is all the current ATSC tuners only support 1080I. If broadcasters started using 1080P then new digital tuners would need to be made and people with old MPEG-2 1080I ATSC tuners could not receive the new 1080P/24 broadcast. The 1080P/24 broadcast would be limited to 19.2Mbps most likely and would require MPEG-4 or VC1.
Verizon FIOS has the bandwidth to offer 1080P if they wanted. They would need a special MPEG-4 digital cable box developed. Since 100% of the movies and most videos come from 1080P/24 digital tape source then the smartest thing would be to transmit the native signal in QAM. A new cable box would need to be redesigned to accept 1080P/24 and output the signal as 1080P/24 or convert it to 1080P/60 or 720P/60 for older displays. If the industry wanted they could offer 1080P programs and the tuners would act just like a BLU-RAY player when outputting the signal. Depending on the TV you own is what the output signal would be.
So far BLU-RAY is the best in picture and sound quality. When buying a display go with the best picture quality, tuners over the years will become outdated since cable and satellite technology changes fast and require new external tuner boxes.

There's some discussion about this in the insiders forum

In summary, it might be possible to use a layered approach and a more efficient codec to squeeze in 1080p60 without inconveniencing current HDTV users.

If and when they do (I would hope within a few years) they will be able to do something the optical disc formats can't, and we'll be back to the point we were just before the optical disc formats launched.

10 years. Plain and simple. Until 90% of the country has HD, which is roughly 10 years, we won't have 1080p on TV, at least not uniformily.

It might actually be closer than you'd think. It takes 6mhz of bandwidth for a SINGLE analog channel. In that same 6mhz of bandwidth you can put in 10-15 digital channels(or 5-10 HD channels). Once everything goes digital in the early part of 2009, then there will be more bandwidth available to Comcast. There is supposed to be 120+ channels in HD by the end of this year thru Comcast. Rumors are that there will be 10 or so channels in 1080P shortly after everything goes to digital.

i'll believe it when comcast delivers it and doesn't charge me for it!!

I don't think they will broadcast in 1080p. What happens to the millions of tv's which can only read 1080i? You telling me my TV with built-in tuner will need a new tuner?

I thought the idea behind it was that the TV made it 1080p, just like the old way we went from 480i to 480p. 480p was never broadcasted, it was always converted at the box.
